' CHANNEL oucr'rnn.

Application filed September 11,' 1928. Serial No. 305,178,

The present invention has reference to a tool especially designed for use by shoe repairmen, the primary object of the invention being to provide a tool for cutting the usual thread channel in the sole of the shoe being repaired.

An important object of the invention is to provide a device of this character including a removable blade and a lateral guide, novel means being provided for adjusting the guide with respect to the blade so that the channel will be formed evenly and at a predetermined point in spaced relation with the edge of the sole.

A still further object of the invention is to provide a tool of the hand operated type which may be moved along the sole of a shoe to accomplish the channel cutting with facility.

With the foregoing and other objects inv view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed. it being understood that changes in the precise embodiment of the invention herein disclosed, may be made within the scope which is provided with a shank that is extended into the handle indicated at 6.

A bore indicated by the reference character 7 is formed longitudinally of the body portion 5 and is disposed adjacent to the outer edge of the body portion, as clearly shown by Figure 2 of the drawing, the ends of the bore being open to permit the blade indicated at 8, to be positioned therein in such a way that the cutting end of the blade will extend beyond the outer end of the body portion so that it may accomplish its purpose, when the tool is moved over a shoe sole.

Extending through the body portion in a guiding finger havingoneend thereof ex- 110 such a way that the inner end thereof will pass into the bore 7, is a securing screw 9 that engages the blade 8 to hold the blade in its positions of adjustment and to regulate the depthof operation of the blade The reference character 10 designates a guiding finger, and as shown, this guiding finger is of a length to extend beyond the outer end of the body portion 5 so that it will rub the outer edge of the sole to be secured and prevent a channel of an irregular character being formed. It will also be seen that due to this construction the blade may be held at 1 ing in the finger 10, the inner end of the lock screw resting in a recess formed in the body portion 5 with the result that after an adjustment has been made, the lock screw 12 may be operated to force the finger 1O laterally and set up a binding action between the adjustingscrews 11 and the threads of the openings in which they move, locking the guide finger in its positions of adjustment.

The cutting ends of the blade 8 are substantially triangular in formation, so that they will dig into the surface of the sole and cut a substantially V-shaped groove or channel to receive the threads employed for securing the sole to the shoe. i

From the foregoing it will be obvious that due to the construction shown anddescribed, a channel may be readily and easily formed in the sole of a shoe at a point adjacent to the edge ofthe sole insuring a true channel for the reception of the thread employed in securing the sole on the shoe.

We claim: e

A tool of the class described including a body portion having a bore disposed longitudinally thereof, a blade disposed within the bore, means for engaging theblade to secure the blade against movement within the bore,

tended beyond the free end of the body portion, screws extending through thefinger and through the body portion for adjusting the" finger laterally with respect to the body p0r- 5 tion, said body portion having arecess in one side thereof, and a lock screw extending 9 through the finger and resting in the recess to hold the finger in its positions of adjustment.

as our own, We have hereto afiixed oursigna- In testimony that We claim the foregoing
